Conditions

Aneurysmal Subarachnoid Hemorrhage

Brief summary

The LD-ITUK is a multicenter, prospective, randomized, double-blind, blind endpoint, placebo-control design trial. All eligible patients with the diagnosis of severe aSAH will be randomly assigned to the treatment group or the placebo group. Patients in the treatment group will receive standard treatment with the addition of lumbar drainage combined with intrathecal urokinase injection started within 24 hours after aneurysm treatment with 30000 IU urokinase, once a day for 3 consecutive days. Patients in the control group will receive standard treatment with the addition of lumbar drainage combined with intrathecal placebo (0.9%NaCl) injection. The primary outcome measure is favorable functional outcome, defined as a score of 0 to 2 on the modified Rankin Scale (mRS), at 6 months after aneurysmal SAH. Primary outcome will be determined by a member of the Independent Committee on Terminal events.

Detailed description

Aneurysmal subarachnoid hemorrhages (aSAH) represent about 8% of all strokes and 9.8 per 100,000 per year in China, which is higher than the overall annual incidence rate worldwide. The cumulative death rate after-onset represent about 24.6% in China, only about 30% survivors will be able to have a good neurological prognosis, the majority of the remaining survivors suffer from long-term disability or cognitive impairment. However, these condition may be even worse in patients with severe aSAH. Studies suggest that early clearance of subarachnoid clot may be associated with a good neurological prognosis. Indeed, subarachnoid clot aggravate the phenomena of cerebral vasospasm and delayed cerebral ischemia in the delayed phase, and promote cell injure within the hypoperfusion zone of the brain in the longer term. Thus, early removal of subarachnoid clot may have a favorable effect on neurological prognosis. Current aSAH recommendations and guidelines advocate the use of lumbar drainage only in case of acute hydrocephalus. The EARLYDRAIN trial suggests that lumber cerebrospinal fluid drainage can early remove subarachnoid clot compare to the standard neurocritical treatment, and improve the prognosis after aSAH. However, the ratio of unfavorable prognosis in severe aSAH is still high. Intrathecal urokinase injection has been proved to effeciently remove the subarachnoid clot, however, no randomized control trials have been conducted to evaluate the improvement of lumbar drainage combined with intrathecal urokinase injection in the favorable functional outcome, defined as a score of 0 to 2 on the modified Rankin Scale (mRS), at 6 months after aneurysmal SAH. The LD-ITUK trial was designed to evaluate whether severe aSAH treated by standard treatment with the addition of lumbar drainage combined with intrathecal urokinase injection have a significantly higher percentage of favourable outcome after six months (score 0-2 on the Modified Rankin Scale) compared to the placebo treated by standard treatment with the addition of lumbar drainage combined with intrathecal placebo (0.9%NaCl) injection.

Interventions

On the basis of standard treatment for severe neurological conditions, within 24 hours of aneurysm treatment, lumbar drainage combined with intrathecal urokinase injection was started. 30,000 IU urokinase dissolved in 3 ml normal saline was injected into the subarachnoid space, 3 ml normal saline was rinsed into the tube, and the tube was clamped for observation for 2 hours, once a day, for 3 consecutive days. Lumbar cisternae drainage Cerebrospinal fluid is slowly and steadily drained at a rate of less than 8ml/h per hour, the daily drainage volume is not more than 200 ml, and the drainage time of lumbar cisternae is controlled within 7 to 10 days, not more than 14 days.

DRUGPlacebo

On the basis of standard treatment for severe neurological conditions, the treatment of lumbar drainage combined with intrathecal placebo saline injection was started within 24 hours after aneurysm treatment, 3 ml placebo was injected into the subarachnoid space, 3 ml normal saline was flushed into the tube, and the tube was observed for 2 hours, once a day for 3 consecutive days. Lumbar cisternae drainage Cerebrospinal fluid is slowly and steadily drained at a rate of less than 8ml/h per hour, the daily drainage volume is not more than 200 ml, and the drainage time of lumbar cisternae is controlled within 7 to 10 days, not more than 14 days.
